My invention relates to car trucks, ltlie in venton having-for one of its objects the provision of'improved means for assembling the centerV bearing carrying Vmembers ofl truck holsters with the underlyingstraps andr a construction whereby the side frames take part in maintaining .theassembly` -ofthese truckIbolster members. In carryingfout this v object of'rmy invention at least one endof truck bolster; and preferably each end theref of, is formed with.; a sleeve that receives 'the Y Y' contiguou'send of the underlyingstrapand a key passing through thefsleeve into holding engagement withfthe strap. The adjacent sideframe lhas aportion which prevents the removal'of the key, the sid'e frame thus tak ing part in maintaining the Vassembly of these two truck bolster members, v i y' The invention vhas for another of its ob-A jectsa' cheapening inA the construction of" bolsters. In carrying out'this object'ofthe 'invention the Istrut that intervenes between I the strap orv tension.men'ibervr and the .comel pression member of the bolsteris-foriiiedv in two upright. symmetrically `Vrelated aparts,

eaclif part having a `wing portion extendingk Vcase of `aftruck bolster thecenter bearing socket and side bearings arepreferably cast integrally with the compression .member which overlies and is riveted orboltedrto said wingsfthe king pin'receiving borev of vthesocket :being continued downwardly into the strut a limited distance by providing vsym-vr 4 f metrically related andinatchedbulges inthe g in connection with'the accompanying drawl upper portion of the strut. VThe bulgedpo'r`` tions of the strut beneath these bulges serve f.

as a rest V'or support for the king pin. s. l, A The invention will be more fully explained lowery end ofthe ing in which Fig; l isla viewv in elevation, partially in section on line ,1f-1 of Fig, .2.,

These uprightv portions?- y totie theftwoiparts :of'stheu strut together. the center bearing carrying member `of aAV The king v:pin receiving A `bore of; the 'socket is continued into the strut by providing symf nietri'cally related-fandV matched bulges 42 l'in the nppeijltportio'n' of n the strut, .the unbulgedV portions lof .the strut below saidbulges serving asa vrest or support forv the lower :end of thereto andfbearing upon the tension inem-` ber-jor strap 5 which lunderlies the 'strut 'i memberendpasses at its ends into the bores of sleeves Glformed at the ends'offthe center from the bolster member l, these lugsf being betweeni-and adjacent the sleeves and engag- Vbearing carrying niemberjl Lugsfdepend ing the topside of thestrap to holdit down.

..4Keysf8 are'passed laterally` through openings that yare formed-fin lthe .sides `of the sleeves",v these .keys having .holding engageyment with the strap throughthe intermedias,

tionof horizontal ridges .9 that are provided transversely upon the ends' ofthe strap to constitute hook formations; The keys are. de#l isirably in the form of lflat bars arranged parallel with the ends of the strap, whereby `any*tendency toy shearing strains between'the keysand. strap is resisted.
